Level 1 adds 4 codewords
Level 2 adds 8 codewords
Level 3 adds 16 codewords
Level 4 adds 32 codewords
Level 5 adds 64 codewords
Level 6 adds 128 codewords
Level 7 adds 256 codewords
Level 8 adds 512 codewords
Using PDF4-17 Example
{PRINT:
@75,10:PD417,YDIM 6,XDIM 2,COLUMNS 2, SECURITY 3|ABCDEFGHIJKL|}
Explanation: Prints a PDF-417 bar code containing ABCDEFGHIJKL with each element .010"
wide and .030" high; each row contains 2 data bytes and uses an error detection and
correction level of 3, which adds 16 error correction code words to the bar code.
